The Wonderlic is usually step 1 and you can find samples on the Internet.  They are usually general aptitude tests, I am not sure how you would study.

What was your major?

I’m a general finance business major.  Thanks for the advice! Joe

Well, I don't see why you would have any problems.  The bigger problem is coming up with your business plan and how you plan to bring in assets and revenue.  Out of college, that is tough.

If you get the chance to work under a Sr. Broker for a decent salary at SB- - -TAKE IT!!!!!.

I actually took the test recently.  It was split into three areas: 

1) Conclusions.  You are given a premise and a conclusion and have to decide whether, based on what you are given, the conclusion (a) is necessarily (totally) true; (b) probably true, but not necessarily; (c) cannot be determined from information provided; (d) probably false, but not necessarily; or (e) necessarily false.  You could probably find some decent practice in a GMAT prep book, for example.

2) Math.  Basic word problems.  I'd brush up on ratios and percent calculations, algebra, and the like.  You are allowed to use a calculator.

3) Personality.  You are given situations that are commonplace in this job, and the answer choices are supposed to reflect whether you have the type of personality that is conducive to success.  Kind of annoying since they say there is no "right" answer, but you know there are answers they want (and don't want) to hear.

Hope this helps.
